Workaround(s)
Manually adding --add-opens=java.base/sun.security.action=ALL-UNNAMED to the vmoptions in Ballista.
This needs to be added to the client-side Java's arguments.

The solution is not to add
--add-opens=...to the command-line options for the client, but instead to upgrade the old janky pre-release version of JAI that shipped with Mirth Connect and still ships with OIE.The other option would be to ignore (and log) exceptions when checking to see whether the clipboard contains an applicable type of data to paste, and just say "nope".
